x>y - What is the ratio of the expenditure of company D to company C ?
81 : 1080 : 1379 : 1185 : 1980 : 11Option E

Required ratio = 80 : 11 - Which of the following companies has recorded the maximum profit in this financial year if the combined income of these companies is 4500 crore ?
54004100250031503250Option A

5% = 750

1 % = 150

45*150/125*100 = 5400 crore - If the income of company D and B together is Rs.270 crore then fined the profit of company B in that year ?
20.1511.7517.1713.3531.20Option B

(20 % + 10 %) = 270

10% = 90

=> IB = 90

E(B) = 90*100/115 = 78.26

=>PB = 11.739 == 11.75 crore - If in the given financial year income of company A was 440 crore. What was the approximately expenditure of company C in that year ?
1022351518Option B

20 % = 440

1% = 440/20 = 22 - If the expenditure of company D is 750 crore, what was the total income of all the given companies together ?
42503300302041254000Option D

20%*100/110*Total = 750
